I know how you feel. Sometimes I get pissed and want to sell the boat. My trouble is not with the inlaws. The actually help take care of the kids when I want to go out on the boat sometimes. The trouble is that my wife has a huge family that is always planning events. If its not this one's birthday it's the other's baptism and so on and so on. More and more it seems I get to use the boat once a month if I am lucky... Sometimes once every two months. It's ridiculous. I feel your pain..
